JAME$ WILSON, OF NElV YORK, N. Y.

PARLOR-GRATE.

Specification of Letters Patent No. 4,191, dated September 13, 1845.

To all whom it may concern:

Be it known that I, J AMES VVILsoN, of the city of New York, in theState of New York, have invented certain new and useful Improvements inthe Manner of Constructing Hot-Air Parlor-Grates, which I denominate theGrecian Grate and I do hereby declare that the following is a full andexact description thereof.

In the accompanying drawings, Fig. 1, is a perspective view of my stove,in front; Fig. 2, a perspective View thereof on the rear side; Fig. 3, avertical section of it from front to back, through its center, and Fig.4, a wall of brick that is made to inclose the fireplace, in a mannerand for a purpose to be hereinafter described.

A, A, is the grate for containing the fuel, and which is to be lined atthe back and ends with soapstone, or fire-brick.

B, B, are sash doors, containing panes of mica; which doors extend downso as to cover a large portion of the front grate bars, which theyapproach, when closed, within a short distance. By this arrangement,when the doors are closed, the draft of air is compelled to pass,principally, through the body of the burning coal, and the fire will berendered clear in front to an extent not seen in grates as ordinarilyused; these doors I usually hinge, but they may be made to slide ifpreferred; in either case they should be made to fit closely, or much oftheir beneficial effect will be lost.

It is a well-known fact that in the use of open grates, the gases, orheated air, from which passes directly into the chimney a very largeproportion of the heat generated in the combustion of the fuel escapeswithout heating the apartment; and such would be the case to a greaterdegree when a grate is inclosed by doors in the manner above describedunless provision be made for arresting it, and diffusing it in the room;such provision I have made by an arrangement of parts to be nowdescribed.

In Figs. 2, and 3, C, C, is a box, or heatedair space, which is peculiarin its construction, being divided by partitions extending along it fromend to end, as shown in the section, Fig. 3. Into the spaces formed bythese partitions, the heated-air tubes, D, D, open at each end of thespace. To admit of a direct draft from the fire into the escape flues orpipes, E, E, there is provided a sliding valve, or damper, a, suchdirect draft existing when the damper, a, is opened, but when it isclosed the heated air is compelled to pass through the tubes or fines,D, D, at each end of the grate, before it arrives at the escape pipe;the damper, a, may extend from end to end of the box, C, so as to allowa free passage; in the section, this damper is represented as closed,and, of course, so situated as to cause the heated air to pass throughthe side tubes or fiues. It then passes directly up from the fire intothe space 22, into which the tubes D, enter at either of its ends. Thesetubes or fiues descend nearly to the bottom of the grate, where theyconnect with the tube, D, up which the heated-air ascends, and entersthe space, 0, into which the escape pipe opens, and communicates withthe chimney.

When the grate is set into a fire place no part of its back, or sides,is to be in contact with the brick work, a space, or chamber, being'leftfor the heating and free circulation of air. At each side, and on thetop of the stove there is an offset, extending back at right angles tothe front, consisting of an open-work plate, F, F, which may be aboutthree inches broad; the back edge of this is to be in contact with thejambs and breast of the fire place. For the discharge of the hot airwithin the fire place a brick wall, Fig. 4, is to be built sufficientlyfar back to stand at the distance of two, three, or more, inches fromthe back plates of the grate, and this wall is to be closed at top so asnot to admit any passage to the chimney excepting through the escapepipe, E. Into this wall, a cast, or wrought, iron plate, G, G, is to beinserted; this plate has a collar on it that receives the escape-pipe,and is provided with fianches allowing of its being removed for theadmission of a chimney-sweeper, or for any other purpose. WVhen thegrate is in place, an air-chamber will thus be formed at the back andends of it where the contained air will be highly heated by the heatradiating from the tubes, D, D, and from all the cast-iron platesconstituting the rear portion of the whole. In close apartments, it maybe found advantageous to provide the means of admitting fresh air fromwithout the room into the middle portion of this airchamber, a damperbeing provided by which to close, or govern its passage.

Having thus fully described the manner in Which I construct my parlorgrate, and arrange the respective parts thereof, What I claim therein asnew, and desire to secure by Letters Patent, is r 1. The manner in whichI have arranged the partitions and damper in the boX, or heated-airspace, C, C, and combined them With the heated-air tubes or fines D, D,at each end of the grate, for the purpose set forth.

2. I' claim the forming of the jambs of the grate With open-Work ofisets F, F, in combination With. the particular arrangements andprovision made for setting the H. H. BENLOCK, FRANKLIN -BROWN.
